Ophelia Sideswipes the North Carolina Coast

September 16, 2005 at 8:30AM Update
Ophelia is starting to move away toward the north northeast, tropical storm watches are up along the coast of Massachusetts, mainly because some of the energy of Ophelia may get close enough to cause some coastal winds.



The waves in the Atlantic are stil being watched as well.
East of the islands (aka 95L) is still holding, about the same chance as yesterday for it to form. I think it wil turn more northward over the next day or two.

The wave north of Puerto Rico is still there, looking a bit better this morning Chances for development there are slowly increasing, but it still is rather low at the moment.

Not really anything else going on, the Gulf is pretty clear, and it's about the time for the African waves to start slowing down, so not much more is expected that way.

Developmental Chances for wave north of Puerto Rico in next two days:
Code:

forget it) 0 1 2 3 4 5 6 7 8 9 10 (sure thing)
[---*------------------]





Original Update
Hurricane Ophelia sideswiped the coast line in Southeast North Carolina, with morehead city getting the most of it on the Northwest and north side of the eyewall. Which is some of the worst of the weather, but if anything good came of it the worst parts in the Northeast and toward the east part of the storm did not make landfall.

You can see an animated radar image of this here (Broadband only!)

And thus the exact center of Ophelia never made landfall. Ophelia finally is now starting to move away from the coastline and eventually out to sea.



Beyond Ophelia we still have the tropical wave east of the Leeward islands in the Atlantic, (called 95L) that is still moving westward and has a chance to become a depression in the next several days.

Chances that the wave east fo the islands will develop into a depression or tropcial storm within the next two days:
Code:

forget it) 0 1 2 3 4 5 6 7 8 9 10 (sure thing)
[-------*--------------]



Beyond that, there is an area northeast of Puerto Rico that seems to be a far edge tail of the former Nate area that will have to be watched, but development chances of that are very low right now.

Re: Ophelia Sideswipes the North Carolina Coast

THE NEXT FEATURE OF INTEREST FOR THE LOCAL REGION IS A LARGE
CONVECTIVE COMPLEX ACROSS THE CENTRAL TROPICAL ATLC LOCATED WITHIN
THE ITCZ. EXAMINATION OF THE PAST 7-10 DAYS OF DATA SUGGESTS TO ME
THAT THERE ARE TWO VORT CENTERS WITHIN THIS AREA OF DISTURBED
WEATHER...ONE A PIECE OF AN AEW AT 47.5W THAT WAS SEVERELY STRETCHED
THEN SPLIT AS IT EXITED AFRICA...AND REMAINS LINKED TO THE TROF AT
56 WEST...AND THEN NEXT A LOW LAT TROPICAL WAVE ALONG 45-46. CIMSS
LLVL VORT FIELDS AND RECENT QUIKSCAT PASSES SUGGEST AN ELONGATED
CYCLONIC CIRCULATION. WEAK ANTICYCLONIC SHEAR ALOFT AND DEEP
MOISTURE WITH THIS FEATURE OFFER THE POTENTIAL FOR FURTHER GRADUAL
ORGANIZATION INTO A TROPICAL CYCLONE OVER THE NEXT FEW DAYS. THE TWO
LLVL VORTS WILL LIKELY HAVE TO MERGE OR CONGEAL BEFORE THIS OCCURS.
NHC COMPUTER MODELS HAVE BEEN SHIFTING BACK AND FORTH BETWEEN AN
EVENTUAL NW AND WNW MOTION THROUGH 120 HOURS...WITH PAST TWO GFDL
RUNS LIFTING STRONGLY N OR NNW. HOWEVER...THIS SYSTEM HAS YET TO
DEVIATE FROM A WLY MOTION. A LARGE MID TO UPPER LEVEL CYCLONIC
CIRCULATION TO THE SW AND ACROSS THE SOUTHERN HEMISPHERE...AND
INCREASING MID LEVEL WEAKNESS N THRU NE OF THE LESSER ANTILLES
SHOULD PROVIDE THE ENVIRONMENT TO MAKE THAT NW AND THEN NLY TURN IN
A FEW DAYS. HOWEVER...THE FARTHER WEST THIS SYSTEM MOVES...THE LATER
THE TURN. THAT BEING SAID...ALL INTERESTS IN THE E AND NE CARIBBEAN
SHOULD MONITOR THIS SYSTEM CLOSELY.


The above is from the NWS discussion in San Juan related to 95L.I am a little worried about this system affecting the islands because of it's low latitud it is located.Let's see what will occur in the next few days.

Re: Ophelia Sideswipes the North Carolina Coast

slightly worse on all fronts this morning, as i'm looking at things.
ophelia hasn't accelerated any ne because the mid-layer ridge to the east is holding. those scenarios where it tries to phase into the westerlies ahead of that oncoming shortwave are looking a little more likely. the ultimate track should be closer to cape cod, and potentially over nova scotia as the nhc official advertises. the longer it waits the more likely that it will move over the cape/nantucket, as well as the chances that it will be a baroclinically enhanced system. timetable for passage is back to saturday night.
95L has continued more to the west. it is moving slow and the synoptic pattern ahead suggests that it will start to gain latitude, but the globals as a group are taking it up to the east of the islands. the longer the system doesn't develop and continues pushing along 10w, the more likely that it won't dodge. several of the dynamic models are also taking a weaker system westward into the caribbean, which would have a different set of implications in the long term (i.e., the system doesn't lift through the persistent weakness forecasted in the central atlantic near bermuda). surely the models lifting the system immediately nw and never letting it past 55w look suspect... i doubt the islands will get off that easy. of note also is the cmc, which has a very powerful hurricane on its 00z run.
a slight complication is the fact that 95L is at nearly 47w, running on a well defined wave near 54w. the 54w wave is on pace to catch the feature stewing north of puerto rico. a small bulge on the upper trough holding the feature near puerto rico has dug ahead of it.. amplifying the shear over the low level turning but also amplifying the ridging east of there. the 54w wave may well catch the feature near 65w over the weekend and consolidate into a low.... as some models are suggesting will happen around sunday north of hispaniola. this feature should be slightly upstream of the upper weakness forecast to camp for 95L, and most models are taking it westward between cuba and florida and into the gulf. among the spread of possibilities is ukmet showing a tropical storm in the central gulf around the middle of next week, to gfs and nogaps having surface troughs in the area, to the euro and canadian mostly losing it. it is telling that the upper air pattern is forecasted very favorable for a tropical system to strengthen over the gulf next week.. if it gets over there it will likely be trouble. ridging near the nw gulf is forecasted to keep it moving westward until late next week, as it weakens and shifts eastward on the gfs in recent runs. if correct this would imply that any existing system would recurve in the western gulf. it's 8 days away or so, but there is reasonable consistency among the models about what a system might do, as opposed to whether it will actually be there. i'm thinking it may well.
weekend/next week likely to be active and interesting.

Re: Ophelia Sideswipes the North Carolina Coast

I have to agree in the short term HF that 95L slides a little further W and S of the models forcast.The system has about 700-800 miles to the islands and looks to be moving at about 15 mph.That being said maybe 3 days at this pace and 95L looks not to be in a hurry to develop.This will give it the lower steering currents and not the uppers the models predict with quick deveolpment.I have not seen the long term GFS yet but the people along NGOM are almost at the point of fatigue myself included.

Re: Ophelia Sideswipes the North Carolina Coast

very good chance it will get into the gulf but right now the wave (96l) should just be a watch and see for the next couple of days. Nothing should develop until maybe Sunday. (95l) should become a TD later today or tomorrow. I feel this will stay further s then forecasted, intrests in Puerto Rico and the islands might have TS warnings go up Friday or Saturday. Hard to give a path more then 3 days out. Ophelia is right on path. I rememberd JB last week had it going across florida into the gulf but he changed that last weekend as he can. Anyone who makes a forecast more then 3 days out has the right to change it and if they make a speculation on something more then 3 days out its just that.Remember the NHC changes their forecasts every 6hrs if changes needed to be taken.

Re: Ophelia Sideswipes the North Carolina Coast

Incredible model agreement in the EPac and Atlantic on tracks and development over the next five days this evening. What you tend to look for in the models is consistency and agreement; we've got both right now.

Right now, all of the current runs that I have seen are developing the following features:
* TS Jova in the EPac, sending it west to west-southwest.
* Hurricane Kenneth in the EPac, sending it west but at a slower rate of speed.
* The feature behind Kenneth, sending it northwest toward cooler waters but also developing it at a decent clip. (Note that if this happens, Kenneth may meet the same fate as Greg did earlier this season, but I'm not sold on that yet...may just be enough movement from Kenneth and separation between the disturbances to keep it from happening).
* The feature N. of Puerto Rico, whether before or after passing through the Fl. Straits on a path for N. Mexico/S. Texas.
* The disturbance (95L; near 11N/50W right now) in the central Atlantic, keeping it north of the Lesser Antilles. (There is another feature behind it near 40W, but I feel that 95L is a better bet right now.)

As noted above, it's not just the first run that these models (GFS, UKMET, NOGAPS, GFDL, Canadian, and FSU MM5) have been showing this particular evolution -- it's about the 3rd or 4th in many cases. That's not to say that everything will happen, but given the active MJO phase coming and what looks to be favorable conditions aloft appearing in the Atlantic in the coming days, it's a good bet something does happen.

Ultimate track on 95L might affect Bermuda down the line; if it gets strong, it'll head out to sea sooner, while if it stays weak, it'll probably get further west. No such luck for the feature near Puerto Rico -- almost assuredly headed west once it breaks off of the end of the upper-level trough it is under. Ophelia heading out to sea should help kick the large trough in the central Atlantic extending down to 20N out and free up the basin for development once again. Water temperatures are still above normal across much of the basin except for those areas affected by Katrina (near-normal at the surface, probably slightly below normal below the surface) and Ophelia (below normal), while the upper-level pattern reminds me a little of that found in June just before things got kicking into July. I'm not saying that we'll see 5 storms in the Atlantic over the next month, but we may likely see another two within a week. Like HF said, the prognosis continues to go downhill with time with regards to further development.

Re: Ophelia Sideswipes the North Carolina Coast

I'm trying to get back on track here. Doesn't seem to be working very well.

Clark and Hank. Thanks for the nightly updates. I now have a feel on whats going on and what to expect for the next week.

Would you happen to have any better news?

Katrina began her turn toward the NW just west of the Loop Current. That's been over 17 days ago. I would think that the currents could have replaced some of the upwelling with warmer water.
Read-dangerous situation west of 89 W. No clouds and very little precip over the Central and Western GOM in several weeks, perhaps months.

slightly off topic
Biloxi TV Met is slowing the cool front/ trough down to a Saturday passage in Biloxi. Originally progged for a Thursday passage. I guess the slower movement could work in our favor (ridge to block the Northern GOM).

I was hoping for about 6 hours of a slow drizzle. The Katrina Tinderbox is as about as dry as it can get.
The NWS here is putting out Burn Ban warnings every 12 hours for the last 4 or 5 days.
The fires out West could pale in comparison to any conflagration that starts here.

You can see the anomalies here:

Katrina's upwelling hasn't been completely undone, but it's nearly there. Before the next system hits that part of the Gulf the SSTs should be back to above normal.

I'm not liking what's out in the Atlantic. Those waves look like they'll develop eventually. Every last one of them. SAL isn't replenishing, and what's there is dispersing. It's not going to impede development:

Re: Ophelia Sideswipes the North Carolina Coast

SSTs recover fairly quickly after a storm's passage, even a major hurricane. That's not true, however, for the sub-surface waters. Hurricanes can affect waters 70-100m deep through mixing processes, with stronger storms able to affect a greater depth. These waters also take longer to warm back up than do the SSTs, whether through currents, mixing, or old-fashioned heating from above. The waters in Katrina's wake are nearly back to normal at the surface -- still below what they were earlier this season, though -- but I would imagine that the below-surface waters are not. This would serve as a cap to the intensity for anything passing through there, whether moving fast or moving slow, though it is likely the waters could still support a category 2 or so hurricane. Not saying that there will be one there, but I think that's about where the true maximum intensity for that region is (under ideal conditions) right now. It'd probably take the rest of the season for the entire depth to warm back up and, with cold fronts starting to make their way closer to the coast, there would be little time for anything substantial to tap those waters. Of course, that brings up the question of a storm forming off of the tail end of a cold front there later in the season...but we'll leave that for the appropriate time.

ophelia almost ready to go, replacements on the way

since its inception on september 6th, ophelia has only managed to move about 500 linear miles. has to be one of the slowest storms i've ever seen. this morning it's further beaten down by shear and entraining some subsidence, but probably going to stabilize shortly as baroclinic energy sources start acting on it. i'm thinking that little lurch to the north this morning is the unsteady beginning of it's last run. not sure if it's going to reintensify in this manner... probably not. the shortwave over the ohio valley ought to grab it later today and accelerate it north-northeast and eventually northeast as it rounds to top of the ridge to the east (which has actually enhanced a little ahead of the shortwave). track should be close enough to the cape cod/nantucket area to give them a shot of wind/rain... and probably a more pronounced event in nova scotia. noticed that watches are up in canada... i guess they're finally letting the hurricane center do their warnings after juan got them in 2003.
95L is still getting a t 1.0 rating, but this should go higher later today as there's a rudimentary banding and a pretty solid convective mass persisting at the sw side of the system. it's likely to develop within the next 24 hrs based on appearance and model support... though the globals as a group have backed away from it just a little in terms of intensity. there's an inverted trough on the base of the ridge to the north creeping up on it and that should start inducing a more nw track as it nears the islands. this morning the center of the feature is around 11n51w, approximately. i'm not sure how close it will actually get as dynamic models take it into the islands and globals as a rule are taking it to the northeast. synoptic pattern days down the road should have it slow down north of the islands and wait on a shortwave near the weakness in the subtropical ridge forecast to persist there.
system ahead of it ne of puerto rico has quite a bit more convection this morning. the upper low shearing it is progressing slowly sw and should keep its development slow and unsteady. a number of global models are tracking it south of cuba right now, which looks spurious. any real system would likely sense the weakness forecast east of florida early next week before it fills.. then probably move west into the gulf, as earlier model runs were progging. as a group most globals are taking this feature into either the yucatan or mexican mainland in the extended period, but if the storm is of any significance it will be further north.
other asides... that little convective burst near 32/46 is on the same old frontal trough as the feature near puerto rico. if it persists it could become a quick flash high-latitude system, but unlikely at this point. some model support also for the wave east of 95L, which is more or less lost underneath an upper trough and in the active itcz, but may become more apparent again further west.
if the eastpac is any indicator, we could have quite a burst of activity. two hurricanes in that basin this morning, with two healthy invests behind them, all parading west. even if the atlantic becomes active, the upper high near the gulf coast and persistent weakness of the east coast should act to keep things mostly away from the u.s. mainland for the next week or so... unless the globals are really missing something.

Re: ophelia almost ready to go, replacements on the way

Hello all...Thought I'd add my thoughts on the two new disturbances now that the Big O has finally starting to move out (did anyone else suffer storm fatigue for this system?) Anyway, on to 95L - Looks better today, still some SW shear to the north but looks like that may be decreasing toward the west. Maybe a trop depression by tomorrow or Sunday. The track, I agree with HF, I don't see rapid intensification like I think the globals were picking up for the last 2 days, so I think a weaker system being guided by low-level flow conditions looks about right. In this case, I agree with the dynamic models (I can't say that very often) and climatology - that this system will move W-NW into the Carribean Sea somewhere south of Hispanola or PR in 3-5 days. Where it goes from there - I won't even speculate on this far out. The second blob of convection NE of PR looks to be enhanced by an ULL immediately to its west. If the ULL moves away or fills in the next two days, I think we'll have a depression. If it develops rapidly, say by 75W, then I think it gets pulled NW toward the weakness in the Atlantic Ridge left over from the Big O. However, all global models show the Ridge quickly rebuilding over the SE US by Monday or Tuesday, so it'll eventually get steered to the west. How quickly it strengthens will have big implications on its future track - more north and then west the faster it forms and perhaps a track west across S or Cent FL, more along a southern tragectory between the Keys and Cuba if it stays weaker. All in all, this storm could be a significant drought buster for west-central FL if it develops quickly.

All the models seem to be playing with the systems at about 21N/65W and 12N/52W. i believe we have a definite LLC in the 12N feature, and a developing one at 21n/65W...on the 12N feature while the global models throw this out to sea the NHC model package keep it more south into the northern islands.
The whole western basin is aglow in color again which usually bodes for increased activity, even a burst in the SW Carribean, which we will need to begin to watch again soon.

ophelia is on the way out, possibly to make room for two more systems. the storm should be approaching nova scotia and becoming extratropical in about 24 hours. it's going to cross some cooler waters on the way, but that should be offset by the baroclinic energy it should increasingly feed off of. probably move over or just east of NS with 50-60mph winds. nantucket may seen ts force winds, but i doubt the us mainland will.
95L could have been classified a depression today. the disturbed weather to the east is probably warping the overall cloud pattern and keeping the t-ratings down, but back when visibles were available you could see the low level circulation and what seems to be an embryonic cdo. now that the system is becoming defined at the surface the track should bend nw soon. globals may be overdoing the nnw track because they're mixing 95L up with the disturbed weather to the east, complements of a weakening inverted trough and oncoming wave. track should be over the central to northern lesser antilles, and the system may well be there late sunday-monday as a tropical storm. a lot of the globals aren't seeing it evolve realistically, and mid-level steering currents are weak, so this system may move nw very slowly for the next few days. it may get to hurricane status near or over the islands. gfs isn't seeing as much of a weakness in the western atlantic in the extended period, and is drawing it westward as the upper ridge over the gulf states amplifies and backs westward as well. this may act to draw 95L's future system further west in the long run, but it's still more likely to recurve.
96L has finally been dubbed. that strikes me as late, because it looked a good bit better earlier. there's a mid-level vortex and upper ridging building over the system, but the convection will have to come back closer to the surface trough. the system isn't developing that quickly and it may be sunday before it's classifiable.. or later. globals are really amplifying that upper high upstream next week, so the wsw movement in the gulf is looking more realistic. if it develops quicker early on it may get hung up on the east end of the ridge near the bahamas or florida. the canadian is probably overdoing it... but most of the other globals that only see a wave by monday are probably selling it short.
it's worth mentioning that several globals are making a new system east of 95L, taking it nw into the open atlantic. that's probably early model run bias... there may be something else that tries to develop out there next week.

Re: O 95 96

If something were to make it into the Gulf are we still looking at a possible landfall in Texas? I forgot what the reason was you said
that might could be a possibility.

the newer models are showing the ridge getting stronger and staying anchored more around texas, so that raises the possibility that it'd just run due west into mexico. still a few days out so the models can change. -HF

should have a TD at 5am

really.... the first sat images after the eclipse just look too good not to give it an upgrade at this point. if it's not upgraded at 5... I'll... I dunno... be very confused I suppose.

But whatever develops would have to take a *really* hard right turn to avoid the islands at this point. Hopefully they're paying attention down there....

95's outflow pattern is looking more impressive, especially in the southeast quadrant:

Re: We now have our 17th Depression

So far all the models are tracking both systems away from Florida. Do you guys agree that that's the most likely scenerio? It's getting too active out there.

Thanks!

Re: We now have our 17th Depression

From my read none of the models show Florida having a problem. But, they have not passed us yet.....

The only reason I think we're OK is because they installed my new electric shutter yestaerday on my big window. Since I paid $6000 we'll never have a storm

uh.... at least one - and possibly 2 - of the models are tracking 96L into or just south of the Keys and then turning it northward. Long term that could indicate an impact in the Panhandle (where I am!).

The soon-to-be TD 17/Phillippe (Lyons on the weather channel was indicating that winds at the surface are already T.S. strength and his prediction was that the system would bypass T.D. status and go directly to T.S.) appears to be an island problem and then a fish spinner, hopefully. Although the models longer term I think turn it back to the west from what I have heard.

i'm wondering which models you're looking at. i haven't checked the dynamical ones, but the globals all pretty much show it zipping out into the gulf wsw towards mexico. i'll go take a look, but think you're mistaken. -HF

Re: We now have our 17th Depression

What has me worried is most the models I see, (may be looking at the wrong ones) don't develop 95l till later and show it going well east of the islands. I can't see at this point how it won't be west of where they all have it gaining strength.

Well since it is already developing... you may be right... although the weather channel is still pointing out that the models have it moving north well east of the islands (which it is already nearing?).... and I don't see much northward movement of the clouds on visible imagery. I think the models are wrong on this one right now, which wouldn't be shocking since it's not yet fully developed.
